Privacy Policy

Last updated: July 2026

LLM Cost Check ("we", "our", or "the site") is a free, browser-based AI token counter and cost calculator available at llmcostcheck.com. This policy explains what data is collected when you use the site and how it is used.

Information we collect

LLM Cost Check itself collects no personal data. All token counting and cost calculation runs entirely in your browser using JavaScript. Text you paste into the tool is never sent to our servers — no prompt, document, or personal information you enter is uploaded, stored, or transmitted to us.

We do not require account registration, do not use analytics tracking, and do not set our own cookies.

Third-party advertising — Google AdSense

This site displays advertisements served by Google AdSense (Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA). Google AdSense uses cookies and similar tracking technologies to serve ads based on your prior visits to this site and other sites on the internet.

As a result of Google AdSense being active on this site, Google may:

Set cookies in your browser to identify your device across sessions and sites
Collect your IP address and approximate location
Use your browsing history to show you interest-based (personalised) advertisements
Use web beacons and similar technologies to measure ad performance

This data collection is governed by Google's Privacy Policy. LLM Cost Check does not have access to or control over the cookies or tracking technologies used by Google.

Your choices and opt-out

You can opt out of personalised advertising by Google at any time:

Google Ads Settings — manage your ad personalisation preferences
Digital Advertising Alliance opt-out — opt out of interest-based advertising from participating companies
Your browser's cookie settings — you can block or delete cookies at any time through your browser preferences

Opting out of personalised ads does not remove ads from the site; it means ads shown to you will be less tailored to your interests.

Children's privacy

This site is not directed at children under the age of 13 and we do not knowingly collect personal data from children. If you believe a child has provided personal information through this site, please contact us so we can take appropriate action.

Links to other sites

LLM Cost Check contains links to external sites (AI provider pricing pages, gateway platforms, etc.). We are not responsible for the privacy practices of those sites and encourage you to review their privacy policies before providing any personal information.

Changes to this policy

We may update this policy from time to time. The "Last updated" date at the top of this page reflects the most recent revision. Continued use of the site after any changes constitutes acceptance of the updated policy.
